Class NormalizedField

java.lang.Object
  edu.washington.cs.knowitall.sequence.SimpleLayeredSequence
      edu.washington.cs.knowitall.normalization.NormalizedField

All Implemented Interfaces:

LayeredSequence

public class NormalizedField
extends SimpleLayeredSequence

This class represents a field of a SpanExtraction that has been normalized in some way, e.g. morphological normalization. A normalized field is a SimpleLayeredSequence with two layers: a token layer, and a POS layer. The token layer contains the normalized words. The POS layer contains the POS tags for those words.
